What is the answer to 13x=32+5x
Ber [7]

Answer:

x = 4

Step-by-step explanation:

13x=32+5x

Subtract 5x from each side

13x-5x=32+5x-5x

8x = 32

Divide each side by 8

8x/8 = 32/8

x = 4

What is an equation of the line that is perpendicular to -x+2y=4 and passes through the point (-2, 1)
Nana76 [90]

Answer:

Step-by-step explanation:

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)

The equation of the given line is

x + 2y = 4

2y = - x + 4

y = -x/2 + 4/2

y = - x/2 + 2

Comparing with the slope intercept form, slope = - 1/2

If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the given line.

Therefore, the slope of the line passing through (- 2, 1) is 2

To determine the intercept, we would substitute m = 2, x = - 2 and y = 1 into y = mx + c. It becomes

1 = 2 × - 2 + c = - 4 + c

c = 1 + 4 = 5

The equation becomes

y = 2x + 5

Which expression is equivalent to (3−2^2) 5 ? 5−3^2 5−2^2 2^2−5 ​ 3^2−5
tamaranim1 [39]
Well (3-2^2)5 = -5
and 5-3^2=-4
5-2^2=1
2^2-5=-1
3^2-5=4
but if you have to multiply them by 5 as well then (2^2-5)5=-5

Find the area of the circle.<br> Use 3.14 for it.<br> d = 6 ft<br> A = [?] ft2<br> A=Tr2
Sedaia [141]

Answer:

28.26  ft^2

Step-by-step explanation:

Area of a circle is calculated using the following formula :

πr^2 (r: radius, and π is given as3.14)

the diameter is given as 6 and radius is equal to half of it so :

(3.14)*3^2 = 28.26  ft^2
